Ha! Yes, I got my Cs and Fs mixed up.

I’m using a WhamBam PEX adhesion plate on my UL2+ to print Polymaker Polylite PETG. It didn’t adhere well at all at 70/80C, so I did an overspray of 3DLAC, which helps. Glue Stick didn’t help at all. I ran a TempTower and the filament prints best at 260F. I’m finding damage to the PEX surface. Can anyone suggest how to prevent such damage or alternative surfaces?

Cura 4.9 would not open and presented a recovery dialog. That dialog was Not Responding when I clicked a button, so I exited the app. When I rebooted my PC, Cura appears to start with no configuration. Is that stored anywhere that I can recover? BRET

Thanks! I'll give FreeCAD a try and start some tutorials. Gotta start somewhere and the sooner the better.

Are there any CAD programs that integrate best with Cura 4.x via plug-in or other means? I’m just getting started and looking to make a CAD choice. Thanks!

Thanks nallath - then I can uninstall V4.4.1?

New to Cura - when I clicked the notification to upgrade my 4.4.1 installation, it put a second 4.5 install on my HD. Is there a way to simply upgrade? Or migrate my 4.4.1 settings over?

Ah - reading that 2.87mm stock filament is advised as swaps are not as easy as just buying the right stuff.

I finally switched from the stock UM 2.78mm spool of PLA to a Hatchbox 1.75mm spool I had on hand. On Machine extruder 1 settings I changed my filament diameter but get failure to extrude. It worked OK for the base of a test cube then stopped extruding. I'll bet I need to change other associated settings. Is there a cheatsheet on settings to change when changing filaments? Thanks!

Success! The feeder motor was completely unplugged from the PCB. I plugged it in E1 and am just now printing the UMRobot. Thanks for the help!

Thanks all - I appreciate the help! I'll work those troubleshooting suggestions tomorrow. It's already Miller Time here in New England. Alcohol and 3D Printers don't mix 😉

I inherited a UM2+ when we acquired another small company. I wiped it clean, lubricated, installed Cura 4.x on Win10, updated the firmware, and did an Atomic Clean. When I try to load the feeder I see no signs the feeder is functioning. I squeeze the tension relief lever and load filament until it is visible in the tube, but the Move Material command doesn't move the material. I don't see or feel any sign the knurled feeder is rotating. Any help appreciated, thanks!
